We have to call rtw8821c_switch_rf_set() with SWITCH_TO_WLG or
SWITCH_TO_BTG according to the chip variant as denoted in rfe_option.
The information which argument to use for which variant has been
taken from the vendor driver.

According to the vendor driver the pkg_type has to be set to '1'
for some rtw8821c variants. As the pkg_type has been hardcoded to
'0', add a field for it in struct rtw_hal and set this correctly
in the rtw8821c part.
With this parsing of a rtw_table is influenced and check_positive()
in phy.c returns true for some cases here. The same is done in the
vendor driver. However, this has no visible effect on the driver
here.

On my RTW8821CU chipset rfe_option reads as 0x22. Looking at the
vendor driver suggests that the field width of rfe_option is 5 bit,
so rfe_option should be masked with 0x1f.
Without this the rfe_option comparisons with 2 further down the
driver evaluate as false when they should really evaluate as true.
The effect is that 2G channels do not work.
rfe_option is also used as an array index into rtw8821c_rfe_defs[].
rtw8821c_rfe_defs[34] (0x22) was added as part of adding USB support,
likely because rfe_option reads as 0x22. As this now becomes 0x2,
rtw8821c_rfe_defs[34] is no longer used and can be removed.
Note that this might not be the whole truth. In the vendor driver
there are indeed places where the unmasked rfe_option value is used.
However, the driver has several places where rfe_option is tested
with the pattern if (rfe_option == 2 || rfe_option == 0x22) or
if (rfe_option == 4 || rfe_option == 0x24), so that rfe_option BIT(5)
has no influence on the code path taken. We therefore mask BIT(5)
out from rfe_option entirely until this assumption is proved wrong
by some chip variant we do not know yet.

Extend 8822c's reserved page number to accommodate additional required
pages. Reserved page is an area of memory in the FIFO dedicated for
special purposes. Previously only one interface is supported so 8 pages
should suffice, extend it so we can support 2 interfaces concurrently.

We would like to make chip_info table const, but 8821c uses one field as

struct that can be read and written.

reported RFE 6, which the driver did not support. Ping-Ke suggested a possible

A second user discovered the above thread and tested the proposed fix.
Accordingly, I am pushing this change, even though I am not the author.

Mapping table from country code to rtw_regulatory, which manages tx power
limit according to countries, is updated. And mapping architecture is also
upgraded. For more precise control on tx power limit, it allows different
rtw_regulatory for different bands logically. Besides, a helper function
to query rtw_regulatory for current band under current country is provided.
For older chips, some newly added rtw_regulatory may not be configured.
To avoid that those chips have no limit on some countries mapping to a
newer rtw_regulatory after table update, a backward selection mechanism
of rtw_regulatory is introduced. It can help chips use a rtw_regulatory
which has been configured as an alternative of a newer one which is not
configured.
In addition, rtw88 actually doesn't manage channel plans by itself.
Instead, it follows them from stack. So, correct some naming about
chplan with regd, and remove the unnecessary channel control for now.

The value of GET_RX_DESC_SWDEC() indicates that if this RX
packet requires software decryption or not. And software
decryption is required when the packet was encrypted and the
hardware failed to decrypt it.
So, GET_RX_DESC_SWDEC() is negative does not mean that this
packet is decrypted, it might just have no encryption at all.
To actually see if the packet is decrypted, driver needs to
further check if the hardware has successfully decrypted it,
with a specific type of encryption algorithm.

Without this patch, RTL8821CE will not have coex support,
and will crash the system because of the NULL pointers
for the coex functions.
While RTL8822C series are WiFi + BT combo chips, it needs
the co-existence mechanism for the device to work on both
WiFi and BT without interfering each other. And the coex
support has already been added before, most of the mechanisms
are implemented. The driver should just add corresponding
functions to operate on different types of chips and its
coex parameters.

The TX power requires to be adjusted based on the thermal value.
The actual power will decrease if the thermal value raised, and
will increase if the thermal value lowered. Driver comapres the
thermal value, as moving averages. If it changes over a limit,
driver will modify the TX power index to compensate.
Implement rtw_chip_ops::pwr_track() for 8821c.

CCK PD can reduce the number of false alarm of the CCK rates.
It dynamically adjusts the power threshold and CS ratio.
The values are compared to the values of the previous level, if
the level is changed, set new values of power threshold and CS
ratio.
Implement rtw_chip_ops::cck_pd_set() for 8821c.

In order to get a better TX EVM, do calibration after association.
The calibration needed for 8821c is the IQK, which is done in the
firmware. Implement the rtw_chip_ops::phy_calibration() to trigger
firmware to calibrate.

False alarm statistics can be used to adjust the RX gain. This
helps the driver to adapt to different circumstances.
Implement rtw_chip_ops::false_alarm_statistics() for 8821c.

Some RX packets contain also information about environment status.
Implement rtw_chip_ops::query_rx_desc() for 8821c. Parse the RX
descriptor which describes the current condition of the received
packet.

To configure the transmit power of 8821c implement trasmit
power index setting callback function for 8821c. This is very
similar to the callback function of 8822b.
